Practice Exercise: Building Envelope Systems

Scenario 1: Factors Scenarion Roof and Oper. schedule

Operating schedule with largest impact

Scenario 2:  Factors:

  1. Thermal Properties of Wall Surface (Wall Construction) for all orientations
  2. Glazing % (Window-to-Wall Ratio) for each orientation (North, South, East, West)
  3. Thermal Properties of Glazing Surfaces for each orientation
  4. Window Shading amount for each orientation

Walls and windows for West, East have  biggest impact on EUI

Scenarion 3:

Plugload efficiency and paybacklimit – with largest impact

Photovoltail measures lead to EUI of 2.45

The EUI value can drop to - 12 EUI if wall optimisation is also considered
